IRON SHEET PILING WALL Filed May 3. 1929 Patented Jan. 27, 1931 UNITED STATES KARL NOLTE, F DORTMUND, GERMANY IRON SHEET-PILING WALL Application filed May 3, 1929, Serial No.

My invention relates to iron sheet piling walls and is an improvement in, or modification of, my invention set forth in my prior Patent 1,690,499 filed on September 30th,

My invention consists in the provision of a special connecting member for connecting the single or box piles of a piling wall.

In the accompanying drawings Fig. 1

shows a cross-section of the connecting member. Fig. 2 shows an alternate construction.

Fig. 3 is a horizontal section showing the manner of connecting single pile and double pile sections in the same wall with the connector of Fig. 2. Fig. 4 is a similar View showing a single section piling wall connected with the connector of Fig. 1.

The improved connecting member, shown in Fig. 1, is substantially I-shaped, consist- 0 ing of a web a and portions 64 and d, the

latter being of greater width than the former.

The web, as shown, is substantially diamond shaped, and the side edges of the portion a are bent inwardly toward the web, as shown at Z), to receive the lateral oppositely extending flanges c of the sheet iron piling sections 0.

The portion d, which as previously stated, is of greater width than the portion a, has grooves e and f, the grooves 6 being symmetrical with the grooves formed by the flanges I), while the grooves f are outside of the grooves e.

In Fig. 2, the construction is, like that of i Fig. 1, an I-shaped member composed of the web it and the portions 2' and k, the said portions being alike, and like the portion (Z of Fig. 1, in that they have the grooves Z and m, corresponding to the grooves e and f.

In connecting the sheet piling, the sections 9 may be arranged as shown at the right of Fig. 3, in box formation, or as shown at the left of Fig. 3, and in Fig. l, in single section formation. The sections of the piling are slightly different, as shown, being indicated at g and g, respectively. The sections 9 have the flanges c, as shown, and previously described, which engage the grooves Z. The sections 9 have flanges 0 similar to the 360,094, and in Germany April 3, 1928.

flanges 0, but single, that is, extending in one direction only. The flanges c of the sections 9 are T-shaped. The flanges are adapted to engage the grooves m, as clearly shown.

In the construction of Fig. 4, the wall is built up with the piling sections 9, each hav- 9 ing at its opposite side edges the flanges 0. These flanges engage the grooves e, and grooves formed between the flanges b and the web., respectively.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that what I claim is 1.. In combination with sheet metal piling composed of sets of similar sections, the sections of one set having at their side edges oppositely extending flanges, and the sections of the other set having at their opposite side edges angular flanges extending in the same direction, and connecting pieces of substantially I-shape, each comprising substantially parallel portions and a connect-- ing web, the inner faces of the parallel portions having grooves near the web to receive the oppositely extending flanges of sections of the first named set, and other grooves outside the first named grooves and spaced apart from the first named grooves and adapted to receive the angular flanges of the sections of the other set, thereby to hold said sections with their flanges in spaced relation and in separate grooves.

2. In combination with sheet metal piling composed of sets of similar sections, the sections of one set having at their side edges oppositely extending flanges, and the sections of the the other set having at their opposite side edges angular flanges extending in the same direction, and connecting pieces of substantially I-shape, each comprising substantially parallel portions and a connecting web, the inner faces of the parallel portions having grooves near the web to receive the oppositely extending flanges of the sections of the first named set, and other grooves outside the first named grooves and spaced aside from the first named grooves and adapted to receive the angular flanges of the sections of the other set, thereby to hold said sections in spaced relation and in separate grooves, the flanges of the sections of the first set extending at an acute angle to the planes of the sections, and the flanges of D the sections of the last named set inclining in the opposite direction to those of the first named set.

3. A connector for sheet piling, comprising an approximately I-shaped member having substantially parallel portions and a connecting Web, the inner face of each parallel portion having a groove at each side of the web, and at least one of said parallel portions having other and deeper grooves located outside the first named grooves.

4. A connector for sheet metal piling, comprising an approximately I-shaped member having substantially parallel portions and a connecting web of substantially diamond shape in cross-section, the inner face of each parallel portion having a groove at each side of the web, and other and deeper grooves located outside the first named grooves and the walls of which are inclined outwardly.

5. A connector for sheet piling, comprising an approximately I-shaped member having substantially parallel portions and a connecting web, the inner face of each parallel portion having a groove at each side of the web, the walls of which are inclined inwardly, and at least one of said parallel portions having other grooves located outside the first named grooves and the walls of which are inclined outwardly.

In testimony whereof I have aflixed my signature.
